I’ll do some more digging, and if you want to email temporary admin account information to me@jacobwg.com, I’d be happy to take a look. It looks like the theme you are using is a premium iThemes theme, so I am not able to easily test the theme code locally.

For those of you other than elementel reading this thread, we communicated via email and discovered that he was in fact running a different +1 button plugin and once we switched to this one, the PHP action code worked.
